Update:

After some research, I found an answer to my question and will post it here, if someone needs it.

The trick is - the "process" callback function expects the results in a format:

[{value: "string1"}, {value: "string2"}, {value: "string3"}]

and not just an array of strings.

$('.typeahead').typeahead(
{ hint: true, highlight: true, minLength: 1 }, // options
{
    source: function (query, process) { // source dataset, data = array of strings
        $.getJSON('Home/Suggest', { query: query }, function (data) {
            //data=["string1", "string2", "string3"]
            //process callback function needs it 
            //in a format [{value: "string1"}, {value: "string2"}, {value: "string3"}]
            var output = $.map(data, function (string) { return { value: string }; });
            process(output);
        });
    }
});
